    摘要: A downhole magnetic debris tool is disclosed that may be connected to the bottom of a packer isolation plug. The downhole magnetic debris tool may include a magnetic shield assembly that shields the magnets and prevent the collection of magnetic debris as the packer isolation plug assembly is run into the well. The packer isolation plug assembly is inserted into the internal seal bore of a set packer. The assembly protects the seal bore from damage and prevents debris from moving downhole. The magnets of the downhole magnetic debris tool may be unsheathed upon removal of the packer isolation plug from the packer. The downhole magnetic debris tool may be used to collect magnetic debris that has collected on top of the packer. Additionally, the magnet shield assembly may act as a debris basket collecting downhole debris while the assembly is pulled from the hole.

    摘要: A selectively communicatable hydraulic nipple is provided which includes an upper and lower communications component adapted to communicate with tools landed inside the hydraulic nipple. Each communications component communicates with a control line used by the hydraulic nipple. An operator is allowed to selectively communicate with tools landed inside the nipple via the upper and lower communications components via the nipple control line. As a result, should the TRSCSSV control line loose integrity, the operator has the option of utilizing the nipple control line to continue oil and gas production without the need for well modifications. Alternatively, an operator could land a chemical injection tool, with an injection string suspended therefrom, in the nipple and inject chemicals into the well via the nipple control line.

    摘要: The present invention relates to a pressure actuated valve for use in well completion assemblies. The valve is operable by pressure between three configurations. In a first configuration, the valve is in a locked-closed configuration. In a second configuration, the valve remains closed but is unlocked. In a third configuration, the valve is open. Also disclosed is a method of installing and operating a three pressure actuated valve in a well completion operation.

    摘要: A valve with the following components: a pipe; an inner sub connected to the pipe; an outer sub connected to the pipe, wherein the inner and outer subs are concentric and define a sub annulus; a conduit between the sub annulus and an inside diameter of the inner sub; a sleeve slideably positioned within the pipe such that in at least one position the sleeve closes the conduit, wherein the sleeve comprises a section of relatively larger outside diameter and a section of relatively smaller outside diameter which define a pressure area on the sleeve between the diameters; and a lock of the sleeve in a position which closes the conduit. A method for controlling fluid flow through a conduit between an annulus defined by inner and outer subs and an interior of the inner sub, the method having several steps: unlocking a sleeve positioned within the inner sub in a first closure position relative to the conduit by sliding the sleeve from the first closure position to a second closure position relative to the conduit; and opening the conduit by sliding the sleeve from the second closure position to an open position relative to the conduit.

    摘要: A well apparatus connected to a pipe string extending down into a cased borehole for treating a formation comprising a packer assembly for sealing with the casing assembly and an integral crossover/release assembly attached to the packer assembly for supporting and releasing a gravel screen assembly before or after treating the formation without rotating the pipe string. The crossover/release assembly includes crossover ports providing a downward flow path for the treating fluid, annular veins providing an upward flow path for the returns, and a reciprocating piston reciprocating upon effecting hydraulic pressure on the piston for releasing the gravel screen assembly.
